The real reason Camilla 'seduced' Prince Charles

Prince Charles and Camilla Parker Bowles’s romance has been controversial from the beginning, and it has no emerged that the relationship may have started as an act of revenge.

Royal biographer Penny Junor has revealed the now Duchess of Cornwall seduced the Prince of Wales in the early 70s to get back at her then-boyfriend Andrew Parker Bowles.

Speaking at the Henley Literary Festival on on Sunday, Junor explained, the man who would become Camilla Shand’s first husband, was cheating on her with Princess Anne, the Prince’s sister.

So in 1971, when Ms Shand (as she was known then) was introduced to the young Prince, she decided to get her own back at the British Army officer.

“So when she was introduced to Charles he thought she was pretty special and he thought she was a bit of all right,” Ms Junor said, according to The Times.

“And she thought ‘Andrew is at the moment off with Princess Anne, I’ll teach him a lesson’ so she had a fling with Charles.”

“There was a lovely story when she was walking through London in the evening and spotted his car parked outside the flat of a very good friend of hers.

“So she let the tyres down and wrote a rude message on the windscreen.”

Ms Junor explained that she wrote the biography with the help of Camilla’s friends, who admitted she was “passionately” in love with Andrew and therefore put up with his philandering ways, which allegedly continued right throughout their marriage.

“He was a cad, he was bonking other people, some of her friends,” Ms Junor said.

However, Ms Junor says the rumour that Charles and Camilla slept together on the eve of his wedding is “nonsense” and that they had stopped seeing each other the moment the Prince got engaged to Lady Diana Spencer.

But it seems what started out as revenge turned to real love, with the pair finally getting married (albeit amid a cloud of controversy) in 2005, with the Duke and Duchess of Cornwall now happily married for 12 years - seven years longer than Charles’s marriage to Diana.
